GONCENTRATOR.

. Application filed January 17, 1921. Serial No. 437,973.

T01 all 'whom 'it may connerie.'

Be it known that I, THoMAs CHanL'roN, a. citizen ofthe United States, residing at Chicago, in the county of Cook and State of villinois, have invented certain new and use-v ful Improvement-s in (loncentrators, of which the following; is a specification.

This invention relates to improvements in concentrators particularly adapted, though not necessarily limited in its use for wet separation of mine-ral elements from each other and from the rock, and is also adapted as a deslimer, and one of the objects of the inv'ention is to provide an improvedA apparatus of this character by means of which a clean and thorough separation of the elements and parts of the material will be affected.

To the attainment of these ends, and the accomplishment of other new and useful ol jects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustra-ting this invention, and in which-\ `Figure 1 is a side elevation showing` two separating elements or units connected together.

Referring more particularly to the `drawings, the numeral 10 designates a support ing structure of any desired size and coniiguration and upon which the mechanism is mounted, carried by the supporting` structure are uprights 11, 12, which are spaced `from each other to receive therebetween one endof a. connecting rod 13. Journaled in the uprights 11, 12, to extend across the space therebetween and at a suitable disof the tance above the support 10, is a shaft 14, and connected with the shaft. preferably intermediate the uprin'lits, is an eccentric 15, and to which eccentric one end of the connect ing rod 18, is connected by means of the usual eccentric strap or bearing; 16.

Theother end of the connecting' rod 13, projects for a suitable distance beyond the uprights and is bifurcated at its forward end as at 17, to form spaced arms 18--19, and between which arms a cross head 20, is pivotally` supported by means of trunnions 21, so that the cross head will be movable with the connecting rod, and also with respect thereto. The cross head 20. is provided with a threaded opening 22, therethrough to receive a threaded boss or projection 23, which is connected with and depends below the `bottom of a separator pan or receptacle 24, se` that the latter will be supported by the connecting rod13.

This pan or receptacle may be of any desired size and configuration, but is preferably rectangular in cross section with the bottom 25, inclininpr` from the sides and ends of the receptacle towards the center thereof so as to direct the separated element which `gravitates to the. bott-oui of the receptacle, towards a discharge outlet opening 26, the wall of which outlet adjacent the bottom of the receptacle is shaped to form a valve seat. The receptacle is provided with a discharge or overflow spout 27, along one side thereof leading from the top of the receptacle, and a cover 28, is `provided for the receptacle. This cover ren'lovably se cured in position in any suitable manner, such as by means of fastening' bolts 29, and a portion of the cover is shaped to form a iiange 30, which extends over and forms a part of the discharge spout 27.

Carried by the cover 28, and depending` therefrom into the receptacle, but terminating a. considerable distance above the bottom of the receptacle and in alinement with the discharge outlet 26, is a stem or guide 3l, which is removably `secured to the cover in any suitable manner such as by means of the threaded extremity 32, thereof.

A tubular valve element 33, telescopes with the guide 31, and is adapted to be moved freely thereupon, one yend of this element 33, being1 shaped to form a valve proper adapted to cooperate with the valve seat around the opening 26, to closethe opening' when the valve is seated and thereby retain the precipitated element within the receptacle until the valve element 33, is shifted to open the out-let 2G.

When the valve element 33, is thus unseated the material will flow through the outlet from the receptacle 24e, and will be discharged through an opening 34k, in the projection 23, carried by the receptacle 24, and will then be received by a chute or delivery conduit 35, having' an enlarged o1' funnel shaped extremity 36, adjacent the outlet or openingy 34, and which chute 35, is supported preferably by the support lO.

rThe discharge outlet 2G, is automatically opened and closed by the valve element 33, by a rising' and falling` movement of the receptacle 2li, and which movement is automatically controlled by the weight of the material accumulated in the receptacle.

To that end the receptacle Q4, is held in its elevated position by means of a scale beam 37, mounted intermediate its ends upon the suitable knife edge bearing 3S, and which beam is connected with the receptacle 9,4-, by means of suitable links 39, two of which are preferably provided. llach link is preferably provided with heads elli-451, the head ell), engaging' in a suitable open bearing' 42, on the scale beam and the head Lil, engages a similar bearing 43, preferably carried by the connecting rod 13, and depending' therefrom. Each of these bearings is provided with an opening' Liet, so that the head 40, may be seated in the bearing from the side thereof, the walls of the bearing being preferably inclined as at 45, so as not to interfere with the relative movement of the link with respect to the bearing during` the operation of the mechanism, as will be understood.

Connected also with the scale beam is an adjustable weight etti, adjusted in any suit able manner such as by means of the adjust ingr bolt or element 47.

An adjustable stop device 48, .is provided for lin'iitingl the movement of the beam in one direction, and this stop device is pref erably carried by the beam and adapted to engage the support 10.

;\ny suitable means may be provided for nnrintainine` the valve element 33, against movement during' the raising and lowerin` movements of the. receptacle Q4., so as to cause the discharge outlet 26, to be opened and closed by such movements of the receptacle. To that end a link 49, is pivotally anchored by one end 50, preferably to the delivery chute 35, by extending,- into the entrance opening 3G, thereof so that a pin 5l, which passes through the wall of such entrance opening will also pass through the end 50 of the link.

The other end 52, of the link passes through the opening 26, in the bottom of the receptacle 24, and into the valve element 33, terminating' short of the end of the guide or projection 31., and a fastening pin 53, extends through the wall of the valve element 233 and also through the end of thc link 49.

rl`hus it will be seen that inasmuch as the valve clement 3?, is held stationary with rcspcct to the support l0, and the chamber is adapted for a pivotal movement about thc eccentric l5, in one direction under the influence of the scale beam 37, and in the opposite direction under the influence of the accumulating; material in the receptacle 2l. the outlet 2G, will be automatically closed and opened, By adjusting the weight ith, upon the scale beam 87, it will be manifest that the weight which is necessary to move the receptacle 2li, by the accumulating' material therein. may be varied at will. A vibratory movement is imparted to the receptacle Q-l, through the medium of the eccentric l5, and the connecting rod 13, and the vibratory movement and rising and fallingg' movements of the receptacle Qi, will not interfere with the operation of either of them.

A vibratory movement is imparted to the 'receptacle for the purpose of agitating the material in the receptacle and for causing; the elements to automatically separate with the result that the heaviest element will gra.'itate through the other elements to be precipitated to the bottom of the receptacle and there accumulate until the outlet 2G, is automatically opened to discharge such accumulation.

in practice it has been found that the vertical or rising and falling' movements of the receptacle 24, will be very slight, due to the fact that after starting the apparatus, there will be an almost constant flow of material from the outlet 2G.

Motion is imparted to the ecrentric l5, in any suitable manner preferably from a motor 5a, and suitable .intern'iediate gear connections 55-s' (-57 and 58, the gear 58 being connected with the shaft 1.4, upon which the eccentric l5, is mounted.

The cover or top 28, is preferably provided with a chamber 59, in communication with the interior of the receptacle QA, and arranged within this chamber is a cup shaped element or structure (30, which is preferablyl separate therefrom and held in position by means of one or more suitable fastening devices 6l, so as to permit the cup to be removed when desired. This cup element is of a size somewhat less than the chamber so as to form an opening G2, to permit the material discharged from or overflowing the cup, to enter the receptacle 24. This cup shaped element is employed for the purpose of intercepting the material as it is fed from a supply pipe or conduit es, alla (t1-eue 'at 'au 5f the mara-a1 ist@ the receptacle, so "that the material Within the receptacle" ivill not` `be unduly agitated thereby, e

"A flexible "ball `and socket joint 649-65, ifs

'providedbetween; the pipe 63 and the cover 28, of the receptacle 24h-so "that the receptacle may bc adapted tor `tre"e n'ioven'ient `ivith respect uto `the pipe :63. l

`Itvis soi'netim'e'sdesirable, according to the materials beinghandled, to impartV to the receptacle 24, lan oscillatory movement 'about the pivots lformed"by the trunnions :21, on 'thefcrosshead"20, in addition tothe `vibratory moveineiit imparted thereto 'by the eccentric l5, and connectingl rod 18. This may `be accomplished in the Vfollowing manner:

e Journa ed upon the upright `11, is a shaft 66, which has connect-ed:therewith a disc 67,provided with a grooveor slot 468, preterablydovetailed, openingkthrough one tace thereo'l. An `element 69, is slfidable'freely 'in the groove by means of its head and the nfree extremity lof the element Iis threaded as at 70. A sleeve 7l encompasses the element 70, so that 'the headv 72, abuts the tace of the disc 67, and the parts are ,trictionaflly gripped or secured ivith `respect to each other bymeans of anut'73, threaded upon the end 7.0,of 'the ele1ne1'it69, and an interposed Washer 74betvveen the nut "73 and the adjacent end of thesleev'e 7l.

lThis element 69 is connected 'with the coveri28, of the VreceptacleQllathrough the medium of a sectional connectiii'g rod, one ofthe sections `75',ii`s.provided at one end With a bearing' which lrecleives the sleeve7l, and "the other Lend j thereof is threaded as `at 76. The `other section 77, is 'biturcated as `at`78,` tofreceive a or projection 79, on the cover 28,"and a pin V80 pivotally connects `the bifuic-ated end olf the element 7 8 with the lug79.

The other end oftheelenientor section 78, lisfthreaded as'at 8jl,"`in a direction Vopposite tothe threads 76, on the section 7 5, and these adjacent threaded j extremities, are adapted to Yreceive a` turn buckle 82;so 'thatbyiadjustingr the turn buckle 82 the length of Ythe connection "rod embodying' thetwosections Y75, ."7, may be "lengthened or shortenedso as to 4vary the tentent of osoillatory movement o`f` the receptacle.

When the turn `buckle 62, isadjusted it `,will cause lthe position of `tlifeff'element L69 in Atorymotion'imparting thereto by the eccentric' 15.

The oscillatory motion is imparted to the receptacle 2a, for the purpose of discharging everything from the receptacle through the spout "30, except the separated element that isto be taken out through the opening` 26. @bviously the degree of oscillation may be varied by rstadjusting the element 69 with respect to the axis of the disc 67, and the angle of inclination of the receptacle may be then further adjusted by adjusting the turn buckle 82.

vVhentl'le element- 69.is secured at the axis of rotation of the disc 67, and it is desired to incline the receptacle Q4, and maintain it in an inclined position, Without imparting an oscillatory motion to the receptacle, this maybe accomplished by simply adjusting the turn buckle 82, until the desired angu larity `is secured.

.The shat't 66 and disc 67, may be rotated preferably vtrom the shaft 14, through the medium of a sprocket chain 8:3, passingover suitable sprockets carried by the shafts latand 66. It is thought that the operation of this machine will be clearly understood from the toregoing;` description, but briefly statedit is as follows:

The element 69, is iirst adjusted with respect to the disc 67 to impart the desired degree of oscillation `to the receptacle 24, and the `motor is then started Which will through the medium of the eccentric l5, and connecting rod `13, impart a vibratory movement to the receptacle at the samel time that the oscillatory movement is imparted thereto by the rotation ot the disc 67. The material to be separated isfed through the pipe 63, and falls into the cup 60, to be delivered therefrom into the chamber 24. The motions imparted to the receptacle 24C `and against the inclined bottom 25 thereotl in such a manner ythat the unseparated material will Iflowor slide across the saidbottom and the top of the accumulated separated element in such a manner that a minimum agitation 4Will be `impart-ed to the accumulated separated element, will agitate the materials to the necessary extent so asto cause the heaviest material to precipitate to the bottom ot the receptacle and there accumulate around the valve element 33.

The other ele-ments will be discharged tl'iroueh the spout 30. lhen there has been a sutlicient accun'iulation ot the separated element in the bottom of the receptacle to overcome the Weight on the scale beam, the receptacle will be lowered, and as the valve element 33 is held stationary, the outlet 26 will be opened to permit the discharge therethrough of the accumulated separated elcment. Then this element has been thus discharged through the openinfr 26, the scale beam will cause the Areceptacle 24 to return to a position to close the outlet 26, and these operations will be continually repeated during the operation ot the machine.

lf desired a plurality ot these separator e-len'ients may be coupled together, and in that event th@ material after separation has been etl'ected thereupon in one unit, will be delivered through the spout 30, into another unit. through the medium ot an intermediate spout S-lf, it desired, for further separation. thus utilizing each unit to remove the heaviest element contained in the material delivered thereto.

The coustructionaiul operation ot each element is the same with the exception olf the specilic manner of delivering` the material into the respective receptacles, and in each unit except the first one, the cover S5 is provided with an opening 86, to receive the end S7 ot the chute 84, and the chutes Se, are bifurcated as at 88, adjacent the end 87, so as to stand astride ot the connecting rods between the respective covers 85 and discs 67. l

lVhen two ot these units are coupled together. a single drive chain S9, may be employed to impart motion trom one of the shatts let, to the discs 67, and it desired an idle pulley 90, may be employed for the drive chain.

Similarly a. single drive chain 91, may be employed to impart motion Jfrom one ot the shafts 14, to the other shaft 14.

rlhis machine may be used as a deslimer by permitting all the mineral elements and part of the rock to pass through the lower opening, and throwing ott through the spout 30, all ot the slime material and considerable ot the tree rock. This will curtail to a considerable degree the necessary separating capacity.

While the preferred form et the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement ot the several parts within the scope of the claims, without departing from the spirit ot this invention.
